Bear is a lightweight remote automation tool for Groovy/Java/JVM. It allows you to deploy projects, setup your cluster, and install software to your remote machines. It differs from other existing tools in that it uses a programmatic approach - your deployment is a regular Java class. It also uses static types, chained method calls, FP, and fluent programming techniques.
